"You think me an old fogey and an old tory": the Tories or Conservative party in the British Parliament generally supported the status quo in the 19th century and resisted major social reforms. The most consequential of these for Ireland, and doubtless the subtext of Deasy's taunt, was the push for "home rule" in the 1870s and 80s.
